net: mdio: aspeed: move reg accessing part into separate functions

Add aspeed_mdio_op() and aseed_mdio_get_data() for register accessing.

aspeed_mdio_op() handles operations, write command to control register,
then check and wait operations is finished (bit 31 is cleared).

aseed_mdio_get_data() fetchs the result value of operation from data
register.
